ABSTRACT:
A system and method for detecting compression of power amplifier circuitry in a wireless terminal and, in response, reducing the output power of the power amplifier circuitry such that linear operation is achieved. In general, the output power of the power amplifier is detected to provide a detect signal. The detect signal is sampled at two predetermined points in time. A ratio of the samples of the detect signal is compared to an expected ratio. Based on the comparison, a decision is made as to whether the power amplifier circuitry is in compression. If so, an adjustable power control signal controlling the output power of the power amplifier circuitry is reduced by one power step, such that the output power of the power amplifier circuitry is reduced by one output power level. The process is repeated until the power amplifier circuitry returns to linear operation.
